While getting ready for some training at Sonic Health my M400 Motherboard dies and i have to start over on a training machine. 

Being somewhat brave I decide to go Vista with build 5840 (Latest candidate for RTM) on my AMD 64 bit computer and must admit was blown away 25 minutes later the computer was finished installing the OS!

Now to be fair this is a fast machine with the Vista Performance Rating it as a 4.1...
